Upsized Spra-Coupe

With its 660-gal. stainless steel or 725-gal. poly tanks, it's the large-acreage grower that AGCO's new 7000 series Spra-Coupe is meant to entice. Overall, the new 7000 series adds more power, boom width, volume and versatility than its 3000 and 4000 series predecessors.

Power train

An electronically controlled Perkins 1106C diesel engine produces 174 hp at 2,500 rpm. Electronic sensors adjust fuel injection with an air cooler for a more complete burn and better power production. The matched cooling package with its side-by-side radiator gives better cooling efficiency than similar-sized stacked designs. A Cat PG115 electronic powershift transmission uses six forward and two reverse gears. An integral torque converter matches engine power to field conditions. Optional front-wheel assist is available.

Suspension/Cab.

An oscillating front axle with independent strut and spring suspension keeps both front wheels on the ground for better traction and ride. The 7450 with its 28-in. tires provides 4 in. of travel, and the 7650 with its 38-in. tires has 6.5 in. of travel. Rear suspension uses a coil spring and knee-action design incorporated into the wheel leg. A chain case design reduces boom bounce and enhances operator comfort while traveling over rough terrain.

The console joystick puts important machine and spray system operating functions at the operator's fingertips. The driver slides it ahead or back to shuttle from forward to reverse while using the gear selector mounted on its back. A floating armrest console places other machine and spray-system function controls close at hand.

The air-ride seat reduces the impact of rough terrain and reduces operator fatigue. An electrohydraulic entry ladder automatically retracts up and out of the way with parking brake release. Engage the parking brake, and the ladder lowers into place.

Spray control

The boom on the Spra-Coupe 7450 offers 42-in. crop clearance and can be raised from 17 to 74 in. above the ground in the low position and 33 to 90 in. in the high position. Boom height on the Spra-Coupe 7650 with its 48-in. crop clearance moves from 23 to 80 in. above the ground in the low position or 39 to 96 in. in the high position. Regardless of boom height, center pivot oscillation keeps it level with the crop at all times, even on rough field surfaces. An adjustable-rate, centrifugal, hydraulic-driven pump ranges from 7 to 85 gpm. A Raven 4000 spray controller mounts on the front right cab pillar at eye level. The controller monitors ground speed and spray volume to precisely deliver product across the boom at rates recommended for product and field conditions.

The 60/80-ft. boom can be adjusted for field width. Retractable tips and fold-over booms are handy in the field and in transport. A five-section boom shutoff and independent left-right boom fold allow operators to modify application swaths as needed to reduce unnecessary overlaps, saving product and reducing chemical load on the environment. An optional stainless steel eductor allows faster product loading from the ground with less risk of spills. A load-sense hydraulic pump with two-speed wheel motors can be shifted as field conditions demand, disengaging at higher speeds when no longer needed. Hydraulic controls adjust tracking width at 2-in. increments on each side to match row widths. The operator can adjust tracking from 71 to 89 in. on the 7450, and 88 to 128 in. on the 7650.

Prices for the 7000 series Spra-Coupes range from around $120,000 to $140,000. For more information, contact AGCO Corp., Dept. FIN, 4205 River Green Pkwy., Duluth, GA 30096, 800/767-3221, visit www.agco corp.com or www.freeproductinfo.net/fin, or circle 200.
